Ernest and his siblings were raised by their governess Lady Charlotte Finch who served the Royal Family for over 30 years. Lady Charlotte supervised the royal nursery and was responsible for the princes’ education until they lived in their own households and for the princesses until they turned 21. After leaving the nursery, Ernest lived in a household with his younger brothers Adolphus and Augustus near the royal residence Kew Palace, and the three brothers were educated by private tutors. In 1786, Ernest, Adolphus, and Augustus were sent to the University of Göttingen in Hanover (Germany) under the supervision of Georg Christoph Lichtenberg, a mathematics and physics professor.

In 1791, Ernest and Augustus joined the Hanoverian army and received military training from Field Marshal Wilhelm von Freytag. Ernest proved to be an excellent horseman and good shot. After only two months of training, Field Marshal von Freytag was so impressed by the progress of his pupil that he appointed him captain in the cavalry.

In March of 1792, Ernest was commissioned as colonel of the 9th Hanoverian Light Dragoons. During the War of the First Coalition (1793-97), Ernest was stationed in Flanders and served under his older brother Frederick, Duke of York, the commander of the combined British, Hanoverian and Austrian troops. During military action in 1793, Ernest received a saber wound to the head which left him with a disfiguring scar. In the Battle of Tourcoing (1794) , Ernest was hit in the left arm by a cannonball and apparently his eyesight was also affected. He returned to England to recover, the first time he had been back home since 1786. Ernest returned to his military duties in 1787. He was promoted to the following military ranks:

1798: Lieutenant General

1803: General

1813: Field Marshal

1801 – 1827: Colonel of the 15th (The King’s Own) Light Dragoons

1827 – 1830 Colonel of Royal Regiment of the Horseguards (Blues)

On April 24, 1799, Ernest was created Duke of Cumberland and Teviotdale and Earl of Armagh. He was the least popular of his brothers and he had a less than favorable appearance due to the facial wounds he had received in war. Ernest had a negative reputation, probably unjustifiably. He was accused of being involved in the murder of his valet Joseph Sellis, of having an incestuous affair with his sister Sophia, and being the father of her illegitimate child. It is doubtful that there was any truth to any of those allegations.

While on a visit to his maternal uncle Karl II, Duke of Mecklenburg-Strelitz in 1813, Ernest fell in love with his first cousin Frederica of Mecklenburg-Strelitz. Frederica was the daughter of his mother’s brother Karl II, Duke of Mecklenburg-Strelitz and his first wife, Frederica of Hesse-Darmstadt. Ernest’s cousin Frederica had a bit of a history which disturbed Ernest’s mother Queen Charlotte. In 1793, Frederica married Prince Ludwig Karl of Prussia, the second son of King Friedrich Wilhelm II of Prussia. The marriage was unhappy, but the couple had three children. Three years after the marriage, Ludwig Karl died from diphtheria.

In 1797, Frederica and Ernest’s younger brother Prince Adolphus, Duke of Cambridge became unofficially engaged. It is unclear whether Frederica jilted Adolphus or if King George III, under pressure from Queen Charlotte, refused to consent to the marriage. In 1798, Frederica became pregnant and the father was Prince Friedrich Wilhelm of Solms-Braunfels. The couple married in order to avoid a scandal, and two months later, Frederica gave birth to a daughter who lived only eight months. Frederica and her second husband had five more children who survived to adulthood. Friedrich Wilhelm was an alcoholic and had to quit the military for health reasons. He lost his income and even his brother advised Frederica to divorce. She was initially against it, but when she met Ernest in 1813, she too wanted the divorce. Before the divorce could be arranged, Friedrich Wilhelm died in April of 1814. For some, Friedrich Wilhelm’s death was a little too convenient, and they suspected that Frederica had poisoned him.

Ernest’s eldest brother George, Prince of Wales had become Prince Regent in 1811 due to the incapacitation of King George III, and so he gave his official permission for the marriage. Ernest and Frederica became engaged in August of 1814. They were married on May 29, 1815 at the Palace of Neustrelitz. The British Privy Council recommended that a second marriage be performed when the couple arrived in England because any children born of the marriage could eventually be close to the succession. Ernest arrived back in England in June to make plans for the second marriage without Frederica, having left her in Neustrelitz. Shortly after his arrival, Ernest received a letter from his mother, Queen Charlotte. The queen regretted that she must refuse to receive Frederica because it was known in England that Frederica had broken her engagement with Adolphus and, to quote the queen, ” the unfavorable impression which the knowledge of those circumstances had made here.” Of course, Ernest was shocked that his mother would do this, but things got worse. Queen Charlotte warned the rest of the family that she would be severely displeased if they received Frederica.

Nevertheless, Ernest returned to Neustrelitz to escort Frederica to England, where the second wedding ceremony was held on August 29, 1815 at Carlton House in London, the Prince Regent’s residence. Ernest’s sisters felt that they could not defy their mother, but his elder brothers George, Frederick, William and Edward attended the ceremony. Ernest and Frederica had one son and two stillborn daughters:

Ernest and Frederica’s son, Prince George of Cumberland at birth, was born amidst the race for an heir to the British throne in the third generation. The death of Princess Charlotte of Wales in childbirth in 1817 left King George III without any legitimate grandchildren. Prince George was born three days after the birth of the eventual heir, Alexandrina Victoria (Queen Victoria), who was ahead of her cousin in the succession by being the child of King George III’s fourth son, Prince Edward, Duke of Kent. After Queen Victoria’s accession to the throne in 1837, Ernest and his son George remained first and second in the line of succession to the British throne until Queen Victoria’s first child was born. Today their descendant Prince Ernst of Hanover is the senior male line descendant of King George III and the Head of the House of Hanover.

On June 20, 1837, Ernest’s eldest surviving brother King William IV died and the only child of Prince Edward, Duke of Kent succeeded her uncle as Queen Victoria. Upon the accession of Queen Victoria, Ernest became King of Hanover. Up until the point, Hanoverian kings of the United Kingdom were also Electors or Kings of Hanover. However, Hanover followed the Salic Law which did not allow female succession. Ernest Augustus, as the eldest surviving son of King George III, became King of Hanover, his wife became Queen Consort of Hanover, and his son George became Crown Prince of Hanover.

King Ernest Augustus of Hanover (Ernst August in German) arrived in his kingdom on June 28, 1837. He was greeted by booming cannons, church bells ringing and cheering people who were glad to have their king in his kingdom after years of rule by viceroys. However, Ernest soon proved unpopular with his anti-liberal style of government. In November of 1837, Ernest issued a patent declaring the 1833 liberal constitution void, and restoring the more conservative 1819 constitution. This patent required all office holders, including professors at the University of Göttingen, to take an oath of allegiance to the King. Seven professors, called the Göttingen Seven, including the two Brothers Grimm, Jacob and Wilhelm, refused to take the oath and encouraged others to protest against the King’s patent. Since they did not take the oath, the Göttingen Seven lost their positions, and the King expelled the three most responsible (including Jacob Grimm) from Hanover.

Queen Frederica died after a short illness on June 29, 1841, at the age of 63. Ernest commissioned the architect Georg Ludwig Friedrich Laves to build a mausoleum for his wife and himself. The mausoleum was built 1842 – 1847 in the garden of the chapel at Schloss Herrenhausen, which was destroyed during World War II. A decision to rebuild the palace was made in 2007, and reconstruction was completed in 2013. Today the mausoleum is in the Berggarten, part of the Herrenhausen Gardens.

The Revolutions of 1848, which led to the fall of King Louis Philippe I of the French, encouraged citizens of Hanover and citizens of other German kingdoms, principalities, and duchies to demand German national unity, freedom of the press, and freedom of assembly. Ernest was initially reluctant to make concessions, but the citizens’ demands threatened to spark a revolution against the monarchy. To prevent a revolution, Ernest agreed to reforms. He appointed liberal politician Johann Carl Bertram Stüve, the deputy of the national assembly in the Kingdom of Hanover and liberal interior minister to create a modern constitution for the Kingdom of Hanover. The new constitution, which came into effect on September 5, 1848, guaranteed freedom of the press, freedom of assembly, the separation of the judiciary and administration, and the equality of all religions. Because of the freedoms granted in the 1848 constitution, Ernest’s popularity greatly increased.

Ernest Augustus died on November 18, 1851, after a short illness. Of his fifteen siblings, only Princess Mary, Duchess of Gloucester survived him. 30,000 people passed by his coffin as he lay in state in the throne room of Schloss Herrenhausen. On November 25, 1851, his funeral was held in the Schloss Herrenhausen chapel. Ernest was then buried in the mausoleum he had built when his wife died.
